This protocol will enable end-users or service providers to develop and deploy real-time, network-aware applications where the network backbone is ATM based, and the backbone is connected to the multimedia terminals over a well-managed local IP network or a dial-up IP connection. Approaches such as RSVP, diffServ, MPLS and IP over SONET are underway to bring real-time services capability to the Internet independent of ATM. However, ATM continues to be the only promising technology in this area because of its ability to negotiate connection parameters and to enforce performance across the network to guarantee those parameters. Our proposal bridges the gap in networks where ATM will be the primary technology used in the network backbone, but not to connect the backbone to end-user terminals.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The HOL effect that the unicast cells experience is not augmented by the multicast cells and the utilization rate of the output ports is increased because both a unicast cell and a multicast cell have the opportunity to be read for each output port. For a fixed multicast rate, the proposed scheme shows 98.9% throughput even though the offered load reaches 1. We designed the proposed shared multi-buffer ATM switch in 0.6 um single-poly triple metal CMOS technology.

Besides the enhanced throughput, the proposed algorithm can reduce mean cell delay by 50% or more and cell loss probability by 90% or more than the random selection scheme.

Existing integration schemes, often called shortcut schemes, primarily map network layer services (such as IP protocol) onto link layer connections (such as ATM connections). Those existing schemes, however, have some drawbacks in scalability and latency when performing this mapping. Therefore, we propose a new scheme in which the features of the existing shortcut schemes are combined to overcome the drawbacks of existing schemes. The proposed scheme is based on the overlay model in the sense that both IP and ATM addresses are used and provide standard ATM connections as direct shortcuts using the ATM address resolved from the IP address. This scheme, at the same time, allows a flexible mechanism for various levels of flow aggregation capability using IP topology information provided by routing protocols such as BGP, OSPF, etc.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The UBR (unspecified bit rate) service category is the most typical service category for the best-effort traffic, especially in the LAN environment. On the other hand, the VBR (variable bit rate) service category with SCD (selective cell discard) option is considered as the service category which is appropriate for wide area networks due to its fairness and minimum guarantee of the cell transmission using not only PCR (peak cell rate) but SCR (sustainable cell rate) and MBS (maximum burst size). However, there is no actual evaluation for such service. We have, therefore, performed the experimental studies on TCP/IP over VBR with SCD service along with UBR and VBR without SCD cases. Through these experiments, we measured the link utilization of the effective data and the fairness between each obtained TCP/IP throughput during congestion of the ATM switch. From the results of the link utilization, the value is always over 90% under the various conditions. Therefore, even in the case of cell losses due to SCD or buffer overflow in ATM switch congestion, the average throughput is almost the same as the value which equals the trunk line speed divided by the number of the accommodated TCP/IP connections. From the results of the fairness, VBR with SCD has almost the same characteristics as UBR and obtains better TCP/IP throughput than VBR without SCD. Finally, we discuss the effectiveness of VBR with SCD and the other service categories, such as UBR and ABR (available bit rate), and conclude that VBR with SCD is one of the most suitable ATM service categories for wide area ATM networks.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

We investigate the theoretical and experimental comparative performance of native ATM and CLIP. We explicitly quantify loss, throughput at the receiver (inversely proportional to delay) and CPU utilization. The key results of this work are: first, we observe a relatively important loss rate for small packet sizes which gets smaller for larger packets. UDP shows larger loss rate than native ATM. For larger packet sizes loss rate tends to zero. Second, for both UDP and native ATM, throughput at the destination is unstable for packets of small size. It reaches equilibrium for packet sizes on the order of 10k octets. Native ATM has a higher throughput owing to the smaller overhead it presents. Third, for both protocols, the CPU is used more at the receiver. At the transmitter, UDP uses more CPU than native ATM, owing to the overhead it introduces across the layers. Those results are further discussed.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

An ideal UPC mechanism must be able to detect any possible violation from the traffic contract. In this paper we use the benefits of fuzzy logic to design a high performance fuzzy traffic controller. In our proposed fuzzy traffic controller, the actual mean cell rate of the traffic source is estimated and the traffic controller is adjusted so its loss load is equal to the generated excessive load. To improve the channel utilization, the proposed fuzzy traffic controller uses feedback from the network to decide whether to pass, mark or discard the input cells. Simulation results show that the proposed fuzzy traffic controller can outperform the traditional UPC mechanisms. It has been also observed that our proposed fuzzy traffic controller improves the channel utilization and demonstrates a low cell loss probability.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.
